The LC4500 Cape provides a portable DLP projector solution for BeagleBone boards. The WXGA projector, controlled by a TI DLPC350, sits below the LC4500 control board. The Beaglebone plugs in "upside down" to the topside of the board. Trigger and synchronization signals are routed to the BeagleBone to support triggering of events. An SPI bus is routed from the BeagleBone to a connector on the LC4500 to communicate with other devices (such as an ADC). Control of the DLPC350 is accomplished with I2C commands from the BeagleBone.

  2. We recommend when re-flashing and SD image file that the BeagleBone is standalone (not plugged in to LC4500).
  3. Install SDCard, Power up with 5V DC power supply (press SXX at power up to load SD Image)
  4. Cover 5VDC power connector with tape !
  5. Make sure LC4500 is configured to support BeagleBone (see xxxx)
  6. Power up LC4500 with 12 VDC. Don't plug in 12 VDC power-supply to BeagleBone!!
  7. Projector will power up with initial splash screen, then switch to BeagleBone X-window screen.
  8. Make sure BeagleBone is connected to network
  9. Connect to BeagleBone with 'ssh -l root beaglebone.local

You can start using the board.
